There can be many advantages and benefits from guest posting. The positive effects of guest blogging include things like earning generic links which are valuable and helping to establish authority in a particular field or niche. Contributing guest posts has had a pretty long and favorable run on many counts, but expert predictions indicate that it is highly likely that they may be next on Google’s list of areas to crack down on. Most of the changes made to Google’s algorithm have to do with cleaning up the web by penalizing spammy practices or those that are along those lines. It is very practical to assume that Google will soon present some way to help clean up guest posts. Just like some of the other areas that have been addressed recently, Google will attempt to get rid of many of the poor quality guest posters.
